Wavlink WL-UG39DK7 disconnect displays after 30 seconds

[borjita]

I have a WL-UG39DK7 dock and when I connect it to my PC (Windows 10 20H2), the display link driver disconnects after 30 seconds, and therefore I stop seeing my secondary screens. The system emits the typical windows sound of when a device is disconnected, and in the device manager you can see how the graphic adapter "USB3.0 5K Graphic Docking" disappears after 30 seconds. The rest of the ports of the dock (ethernet, usb, etc.) continue working correctly.

I have tried with a second PC but the result is the same. Any idea what it could be?

PS: attached video of the problem and logs of displaylink support tool

Thanks a lot.
